STRAP, BAND, AND THE LIKE.

Specification of Letters Patent.

Patented Aug. 6,1907.

Application filed Tannery 26, 1905. Serial No. 242,609.

Figure l of the drawings shows in elevation a dragband or brake-strap for the warp-beam ol a loom. F ig. 2 is a detail view on a larger scale than Fig. 1, showing a portion ol' a strapdiand or the like constructed in conformity with my invention.

The invention has reference, more particularly, to the drag or brake-straps or bands which are employed in connection with the warp-beams ol looms lor the purpose of controlling the delivery of the warp-yarns as the weaving proceeds, and to other straps, bands.

cords and the like which are employed in the textile industry. Straps, bands, cords and the like made of fibrous material are affected by the hygroniotric condition ol the surrounding atmosphere. When the atmosphere is humid, they absorb moisture and contract in length. This affects their action more or less When employed as drag-bands, straps or the like, and in various other situations, it being necessary in many instances to offset the change of length by a compensating shift or adjustment At the present time, the practice-is general of maintaining the atmosphere within a cotton mill by artificial means in a predetermined state of humidity, inasmuch as the cotton fiber can be worked with better results, especially in the production of yarns of the fincr counts. The degree of humidity which is desirable for the latter reason causes difficulty to be experienced in connection with let-off straps or hands, etc.

One general objectof the invention is to obviate the difficulty to which reference has been made.

Another general object thereof is to obviate the tendency' to stretch which is experienced in connection with straps, etc., composed of fibrous material. l

in attaining the general objects aforesaid 1 make a strap, band, cord or the like with a non-extensib1e core,

1, of suitable material of a degree of flexibility vary-i ing according to the contemplated use of the strap, band, etc. For some purposes I employ a strip or band of sheet-metal, for others a strip or band of vulcanized fiber, and for still others one or a plurality of wires of greater or less softness as the intended use may require. The core-strip or band, wire or wires, etc, I coat with glue, shellac, or the equivalent thereof, for the purpose of causing the fibrous covering, 2. which is applied to the said core to adhere firmly to the latter, so as to obviate tendency of the said covering to slip along the core. The covering is composed of fibrous matel l l rial, usually in the form of yarns, and is woven, braided, wrapped, or otherwise formed thereon or applied thereto. The said covering I treat with paraflin or its e uivalent, either alone or combined with one or more additional substances according to the results which it is desired to secure in practice. In Fig. 2, the portion 3 is assumed to have been thus treated.

ln oractice the fibrous coverin will be treated throughout the length of the strap, band, etc. The paraffin or its equivalent renders the fibrous covering non-absorbent of moisture. \hen the strap, cord, or band is designed for use as a drag-band in connection with the warp-beam of a loom for the purpose of con trolling the unwinding of warpvarns, I combine graphite or other suitable dry lubricant with the parafiin before applying the parafiin to the fibrous covering. For the purpose of making the application of the parallin to the covering, l. melt the former and while the same is in a melted or softened state I. mix therewith the graphite or other substance which is used. The strap, band, cord or the like, then is caused to pass through the melted wax or compound, the fibrous covering taking up the desired amount thereof and'becoming satu- .ratcd therewith. The non-hygromctric properties of the st ap, band, cord or the like, thus produced cause. it to continue unchanged in length, etc, by the conditions as to moisture of the atmosphere in which it is employed. When graphite or the like material having lubricating properties is employed, uniformity of eti'eet in its action in connection with the warpbeam is thereby secured. Straps-or bands made in conformity with the invention are excellently adapted for employment for loom-strapping such as lug-straps, jackstraps, etc., and also for belting. For lug-straps and jack-straps,'the graphite may be omitted if desired, the fibrous covering being treated with parailin alone. For belting, the place of the graphite or other dry lubricant will be occupied by powdered resin melted with the paraffin or other wax prior to the saturation of the fibrous covering therewith, the resin or its equivalent being employed to enable the belting to take firm hold of the pulleys over which it passes.v A cord or the like made with a center or core of one or more soft wires, with a winding of yarn or cord, and treated with the paratiin and resin, adapted for use as spindle-banding.

I claim as my invention:

1. A strap, band, or the like, comprising a non-extensible core and a covering of fibrous material treated throughout with paratlin.

2. A strap. hand. or the like, comprising a core, and a covering of fibrous material treated throughout with paraftin and graphite.

3. A strap, band, outhe like, comprising an inextensible core. and a covering of tihrous material treated throughout with paraffin and graphite.

4. A strap, hand, or the like, comprising, n corev and a strap, bund, 0r the like, comprising a n0n-extensible {core and a fibrous severing which is boundto the said core by gIue or sheliaic-"rmottreated througheut with paraflin Illlfi graphite. 1

ii A strap, band, or the like, euinprisinga non extensibie core and a semiiless covering 9f fibrous material which is bound to the said core by lue or shellac anti treatedwith pm'u iin and graphite. 7

T. A strap. band. or the like, comprising a non-extensible core and :1 seamless covering of ,fi'orous material treated with parziiiiu and graphite. v

8. A strap. hand, or the like, comprising 51 men-extensible core and a seamless coveringof iibrous material treated u'iih parafil 9. A strap, band, or the like, comprising a core, and a seamiess covering of fibrous material treated with parafiin and graphite;

10. A strap, band, or the like/comprising an inextensible core, and .a seamless covering of fibrous material treated with paraffin and graphite.

'11. A strap, band, urtlie 1ike,'c0mprising h core, and a seamless fibrous overing, bound to said bore by glue or sl qelinc, and treated with parufiin and graphite. I In testimony whereof I uifix my signature in presence'of two witnesses.
